This invention pertains to, an improvement in a removable metallicradiator shield, more ted between the individually assembled sections ofthe radiator subsequently to the sembly of the radiator.

It is appreciated that the use of sheet metal shields for heatingradiators has been previously resorted to, but, to my knowledge, therehas not yet been produced a radiator shield which will be as easily andrigidly applied as that embodying the principles of my inventiondescribed herewith.

One of the principal purposes of this invention is to provide for ashield which can be conveniently and yet firmly fixed to the radiatorsections when assembled, forming an integral radiator unit.

Still a further object is to produce a shield which is relatively cheapto manufacture, simple to remove when desired and at the same timeunlikely to become accidentally dislodged during or after installation.

A; shield constructed in accordance with my invention may be installedin the usual radiators and is particularly adapted to the type radiatorwhich will be hereafter described. Other advantages will become apparentin considering the following description given in connection with theaccompanying drawings in which: 7

Fig. 1 is a vertical transverse view between two adjoining sections of aradiator and shield made in accordance with one embodiment of myinvention.

Fig. 2 is a top view of three sections of a radiator, assembled with theshields between the sections, and

Fig. 3 is a side elevation of a portion of a radiator provided withshields embodying my invention.

Referring to the figures, the assembled radiator is composed of a numberof sections 2, each of which is made of cast metal and formed to providea number of communicating passages, through which the steam or otherheating fluid passes to radiate heat through the shell or metalthickness of the radiator. The sections 2 are joined by means 1936..Serial No. 449,508.

of the usual number of threaded nipples, not shown, contacting at thepoints 3 and 4 for the upper and lower communications, respectively,Each of the sections is preferably made with parallel spaced ribs 5,which form grooves, therebetween as shown, to receive the radiatorshield although a single rib as is usual in radiator construction willsutlice.

The shield 7, formed of a strip of suitable sheet metal, and preferablyof concave in cross section, as indicated at 8, and of proper width tofit between and follow closely the I guides formed between the ribs 5.The end portion of the stripis bent over to form a top section 9. Theangle of bend is preferably slightly less than a right angle beforebeing i installed. This is done so that when the shield is pressed intothe assembled sections 7 from the top it is necessarily sprung slightly,making it more rigid and tight.

It is unnecessary, therefore, to provide for any special form ofshearing at the points 10 and 11 which are merely rounded, respectivelyat the upper and lower ends of the shield, thus facilitating productionwithout regard to a special fit or form for the purpose. Being concavein form, the surfaces 8 and 9 of the shield 7 afford a relatively easiersurface to clean than those heretofore produced. At the same time thisconstruction lends itself so readily to a convenient and effectiveinstallation, the rounded ends 10 and 11 aiding in the insertion of theshields between the radiator sections.

It is obvious that many changes may be made in the details ofconstruction without departing from the spirit and scope of thisinvention as defined in the claims appended hereto.

I claim:

1. A metallic radiator shield capable of being removably held betweensections of a heating radiator, said shield consisting of a longitudinalrelatively long strip having its 9 outer face concaved throughout itslength vI and having an end portion bent to form a lateral end portionof similar cross section, said shield being adapted to provide arelatively smooth surface betweenand continuous with 100 the outersurfaces of adjacent radiator sections. 7

2. A metallic radiator shield comprising a relatively long strip havingits outer face concaved and having an end portion bent at slightly lessthan a r ght angle to the remainder of the stripto form a short lateralend portion of similar concaved section, said concavity tending toproduce compression between said shield and opposed sides of ad jacentradiator sections in both lateral and longitudinal positions, saidshield also being adapted to provide a relatively smooth surface betweenand continuous with the adja cent outer surfaces of adjacent radiatorsections.

In Witness of the foregoing I aflix my signature.
